发明名称 JIG FOR MEASURING LASER POWER OF OPTICAL DISK DEVICE
摘要 PURPOSE:To enable measurement to be made with an improved working efficiency and accurately by the use of a measuring jig for laser power of an optical disk device. CONSTITUTION:The body of a jig 11 has virtually the same shape as that of a case where an optical disk is housed. A filter 25 and a photoelectric conversion element 20 are provided within the body of the jig 11. A laser 45 which is emitted from an optical head 6 passes through the filter 25 and is attenuated and then irradiates a photoelectric conversion element 20 with an illumination within a proportional operation region.
